Im so sorry you went through this,
nice dedication

I'm sorry you had to go through this.....

I know this is a song, but it repeats to much, to make it better try describing what your cousin was like, kind of like this:

"Always making people laugh and smile"

Or something to that extent...

But otherwise good job, you could make this into a better song and add a lot more about your cousin and how great she was to have around, you get what I'm saying, so good job!

Im sorry thats really sad :( 5/5 i can see it being a song :)
